atomic_inc, atomic_inc_32, atomic_inc_uint, atomic_inc_ulong, atomic_inc_ptr, atomic_inc_64, atomic_inc_32_nv, atomic_inc_uint_nv, atomic_inc_ulong_nv, atomic_inc_ptr_nv, atomic_inc_64_nv -- atomic increment operations SYNOPSIS
#include <sys/atomic.h> void atomic_inc_32(volatile uint32_t *ptr); void atomic_inc_uint(volatile unsigned int *ptr); void atomic_inc_ulong(volatile unsigned long *ptr); void atomic_inc_ptr(volatile void *ptr); void atomic_inc_64(volatile uint64_t *ptr); uint32_t atomic_inc_32_nv(volatile uint32_t *ptr); unsigned int atomic_inc_uint_nv(volatile unsigned int *ptr); unsigned long atomic_inc_ulong_nv(volatile unsigned long *ptr); void * atomic_inc_ptr_nv(volatile void *ptr); uint64_t atomic_inc_64_nv(volatile uint64_t *ptr); DESCRIPTION
The atomic_inc family of functions increment (by one) the variable referenced by ptr in an atomic fashion. The *_nv() variants of these functions return the new value. The 64-bit variants of these functions are available only on platforms that can support atomic 64-bit memory access. Applications can check for the availability of 64-bit atomic memory operations by testing if the pre-processor macro __HAVE_ATOMIC64_OPS is defined. SEE ALSO
atomic_ops(3) HISTORY
The atomic_inc functions first appeared in NetBSD 5.0. BSD
